Robert, they are Andy Strapz panniers. They are very good, definitely recommend them. Easy to fix to a frame with rock straps.They are very tough and waterproof ( up to a certain point!) . I have used them for all my trips for the last few years.

Perfect. They look very good and the price is more or less reasonable. I am also considering some horseshoe-like luggage like Giantloop Coyote. Have you considered or tried something like this?Thanks a lot!

No, I bought my panniers a while ago so no need for anything else. However, last year, when we rode in the Altai, our friend Anton had (Russian made) horse-shoe panniers like Giantloop, and it was very good on rough trails. He seems to like them.
